Thermal vision highlights Uranus's rarely-seen rings

Thermal images taken of Uranus, showing the planet's rings clearly

Although Saturn sports the most impressive ring system in our neighborhood, it’s not alone. Uranus is also packing some rings, although they’re usually too faint to see without a powerful telescope. But a striking new set of images shows these rings in very clear detail thanks to thermal imaging, while also allowing astronomers to measure their temperature for the first time.

NASA gives go-ahead for mission to explore ancient planet core in asteroid belt

Posted on by

NASA has given its approval to start construction of a spacecraft that will one day explore the metallic asteroid Psyche, which may represent the exposed metallic core of what was once a Mars-sized planet. The probe is set to launch in August… Continue reading NASA gives go-ahead for mission to explore ancient planet core in asteroid belt→

Dusty, gassy origins of giant planets observed at last

Posted on by

An international team of physicists has finally found proof of circumplanetary disks, adding substantial weight to current theoretical models of planet formation. These disks of gas surrounded by dust have eluded detection, until now. ..

New algorithm digs up 18 Earth-like exoplanets from old Kepler data

Posted on by

So far almost 4,000 planets have been discovered orbiting stars other than the Sun, and that tally is constantly growing. Now another 18 exoplanets have been added to the haul, but the difference this time is that all of them are roughly Eart… Continue reading New algorithm digs up 18 Earth-like exoplanets from old Kepler data→

Unicycle Given a Hand Crafted Gear Box

Posted on by

Being able to coast on a bicycle is a feature that is often taken for granted. The use of a freewheel was an improvement made early in the bicycle’s history, for obvious reasons. This also unlocked the ability to build bikes with multiple gears, allowing higher speeds to be easily reached. On a unicycle, however, there’s no chain and the pedals are permanently fixed to the wheel’s axle, meaning that there is (usually) no freewheel and no gearing. [johnybondo] wanted to get some more speed out of his unicycle, though, and realized he could do this with his own homemade …read more
